The sections can then be replanted into the ground or in containers.
Propagation by Bulbils
Drimia purpurascens Jacq.f. produces bulbils - a small bulb that grows above the ground and develops into a new plant. These bulbils can be used for propagation. They can be carefully removed from the main plant and planted into the soil at a depth of about 2 inches. The soil should be moist, and the bulbils should be kept in a shaded area until new growth appears.
Overall, Drimia purpurascens Jacq.f. is an easy plant to propagate, and with the right care and attention, you can grow several new plants from just one. Propagation by seeds, division, and bulbils are all simple methods that can produce healthy and robust plants.
